Comment 8 for bug 439768

I also face this problem in my MSI Wind U100. This netbook also has bug #435352 but I think the two issues are not related. It happens quite randomly and typically stops when you either switches terminals, login, change brightness, etc. I would say it is just the issue described in

Since it is quite notorious and is a regression from previous behaviour I would increase the importance of this bug and nominate it for karmic release.
